Ferrite cores / Nanocrystalline Alloys cores etc.


Non-split type


Impedance is not lowered by current superimposition (current: 20A or less) since the saturation magnetic flux density is higher than ferrite cores. Possible to suppress normal-mode noise.
Impedance is stable from –40°C to +85°C, with a high Curie temperature.
Resin coated core protects cables from damage caused by core edges.

  • Ferrite core (Noise filter)
  • Common mode noise suppression



Feature Non split type Cable types Round cable
Frequency band Power line noise Usage For conducted disturbance, Heat resistance
